What is the Best Tool to Measure Cartridge Azimuth?

What do you use to measure / set azimuth of your cartridges and / or styli? I am afflicted with diminished eyesight, so aligning the azimuth of the stylus by eye is not practical.

To that end, I’ve use a simple bubble level (spirit level) about 1-1/2” in diameter to get the headshell as close to level as possible, after first leveling the platter by adjusting the turntable feet. 

I figure some clever lever engineer has made an easy to use electronic tool for this purpose, but I haven’t found anything in my searches. Nature abhors a vacuum, so one day if not already, it might surface. 

Until then, does anyone have alternate methods? How about using a test record? Is that feasible? I do have a couple of good oscilloscopes by the way, so I can make precise measurements of levels, phasing, frequency, etc....

I have had good luck with the “SMARTstylus. www.acoustical-systems.com

I would not recommend setting azimuth by using any combination of any bubble levels.   The opportunity for error is too great.  After all is said and done, it is not really a bad idea to set the cartridge visually typically using a mirror so that the cantilever is at a 90 degree angle to the surface of an LP.  For most well made cartridges from reliable manufacturers, this will work fine.  If one is crazed enough to want to set azimuth electrically, you can use a Fozgometer for sure or any of a few other methods for minimizing crosstalk. To do this, you need a suitable test LP that has bands with signal only in one and then only in the other channel.  Based on what you say about your equipment, you probably can figure out how to set for minimal crosstalk.

I second the use of the Foz and its accompanying test record.   The results are super

AnalogMagik looks intriguing but having to spend $750 plus another $75 plus tax, and no support unless you buy a “$150 Lenovo” from them seems extremely suspicious. You simply cannot get a usable laptop for $150. Their literature is written by someone who is borderline illiterate, which also seems their product seem as genuine as an email from a Nigerian “prince” who has millions of dollars for you.

The Fozgometer ostensibly could be replaced with a decent oscilloscope, so what is it’s benefit to someone who already owns a couple of high-end oscilloscopes? Don’t take my question as being combative, I’m just curious if the Fozgometer has any unique qualities that lend it to being better or easier to use for the task.
